Here are the details of a crazy but winning hand I played last night. We were the last three players of a 10 player SNG. Did I take too big a chance with these Aces?

Obviously, I was worried about the Aces being cracked by the flush. On the other hand, I figured I had a ~36% of hitting the nut flush myself. Did I play this right, or was I just a lucky fool?
